I found this bike on Craigslist, always a sucker for chain stay mounted u-brake vintage bikes. Bristol Avenger MTB, I am guessing late 80's bike. Some neat features dual down tube water bottle mounts and maybe shoulder strap braze on the top and seat tube.

I have never heard of Bristol, maybe from the UK? Anyone? Bueller?
